To all whom. it may concern: 1

Be it known that we. .\t:ors'r l.\uu's Kaannsuaalm. manufacturer. and (.uu. Stu-1m EN Jt'Lits 'msn, managing director. suhjects of Denmark. residing at No. 28 Frederikssundsvej; (.openhagcn. llcmuark. and No. 18 \"cstergade. ()dcn c. lh-nmark. respectivcly, have invented new aml useful lmprovcments in Absorption \pparatus for lee aml Freezing Machine of which the follow- The present invention relates to absorption-aptntratus for such iccand freezingmaehines by which through raretiu-tion of the air and consequent evaporation of a tluid a low temperature is produced.

The invention consists in giving; the inside of the ahsorption-receivtu' such a shape that the absorption lluid is spread over a large surface, and that the air passing through the receiver is forced to come into contact with this largesurt'ace ol' the fluid. By this means the absorption-fluid quickly absorbs all of the vapor containcd'in the air.

The invention is illustrated in the accompanying drawitr; in which:

Figure l is a vertical section through an ahsorption-receiver connected with a decanter the water in which is to be cooled. Fig. .2 illustrates a modified form of the upper part of the absorption-receiver. Fig. 3 is'a side-elevation of the apparatus in connection with an air-pump. and Fig. -l is a plan view of Fig. 3. 7

The air-pump a (Fig. 4) is in the described form for the apparatus driven by a crank a mounted on a shaft. 7). The ahsorption-recciv r I1 is incloscd in a hood 1' which is carrietl partly by a swing-axle turnahle on two pins partly by the one arm of an angle lever is turnahle on a pin II. The angle-lever is by a comiecting-rod m connected with a pin on a wheel it carried h the axle at 'hcn the axle It is turned. the rec iver 1/ will I move to and fro on the pins 5/ and It. The receiver II is, in order to follow these movemcnts, connected with the suetion-chamber of the air-pump a hy means of an india-rtth- I I her-hose 71;

The fluid containing chamber q which in the '1 present instance is a decanter in which the air is to be rarefied, is placed in a basket 1' which is arranged to rock on an axle s and-connectedwith receiver rl by means of a flexihle hose t-. The receiver 11 which generally is of glass and contains sulfuric acid or another water altsorhine tluid i cylindrical with rounded taunularie between the sides and the tt m and the cover. From the cover 1'' projects downward a somewhat ohliqne conical plate H which ctmtinues the roundinglit-tween the sidc-wal and cover and forms an annular chamher H with the cover if. this chamber heme provided with a small ln':\m-l|-ptpe '1. has an opening to which is applied a pearshapcd retort 1,1 pro ecting into the reccner. the neck of the said retort lgcmg (:tl'littl with i but little play through anopcn'ing in the plate a. The neck of the retort y is conical an shaped for connection with the conical end of the hose t. The bottom of the retort.

7 is in the. middle curved slightly upward so that it forms a flat. cone Lat Who e lmtlmll a row of holes 2 is arranged. The water ahsorbtng: liquid 3 m the receiver 1] reaches closely to the bottom of the retort. 1 \l hen 4 the receiver 11 is moved to and fro, the lluid f i) will rush along the wall and through the i medium of the plate 11 it will be Carried along to the retort 1 whose total surface will he constantly wetted by the liquid. The air sucked out from the chamber q through the hose t passes through the holes ".2, strikes against the surface of the fluid, ascends into the receiver at where it on all sides is surrounded by the water-absorbing fluid and will finally pass through the annular opening where it. as a thin sheet must pass through the liquid flowing down from the plate 1/. so

, that. it comes into intimate contact. with the water-absorbing liquid.

Fig. 2 shows another simple form for the spreading-device. The annular chamber to 1 is here formed by the bent. or blown wall '0 itself. Instead of the peat-shaped retort a double-walled cylinder y can be used upon which is titt d ,the hose The over 111;, IS a specification.

whose outer wall togetherwith the inwardly bent part 7: of the wall '2. forms the narrow absorption-space The hose t is at both ends supplied with cones one of which, 4-, is placed in the neck of the retort, 31 and held there by straps :7 fastened to the lower part oi the hood f. These straps 5 pass througl-i holes 6 in the .cover ofthe hood whereupon a ring 7 at the end of each strap is hooked on to a hook S upon the hose t. The other end 9 of the hose is put into the neck of the decanter I v The decanter q is together with the tank (I the receiver at and absorbed by the liquid 3 whereby the low )ressure in the dccanteri will be maintaine The evaporation will then re-con'nnence and the temperature of; the water in the decanter will quickly decrease.

The whole apparatus is very compact and can be easily mounted on a board 10 or the like.

Having now particularly described and ascertained the nature of this said invention and in what manner the same is to be performed, we declare that what we claim is:

1. An absorption a 'iparatus comprising a receiver, a perforated retort mounted in the receiver and projecting through an annular chamber formed in the top of the re"eiver and connnunicating with the latter through an annular opening in the bottom of the chamber, a'fluid container, a flexible coni duit connecting the latter with the retort, an air pump, and a flexible conduit connecting the pump and annular chamber. 1

2. An absorption apparatus comprising a receiver, a retort having perforations in its bottom, mounted in the receiver and projecting through an annular chamber formed in the top of the latter, said chamber communicatingavith' the retort through an annular opening, aswinging receptacle for the receiver, alluid container, a rockable sup-' port for the latter, a flexible conduit con necting the container and retort, an air pump, and a flexible conduit conneetingthe pump and annular chamber.-

3. An absorption apparatus comprisin a. cylindrical receiver having rounded cn s and an annular chamber formed in its top,

a retort mounted in and communicating with said receiver, a swinging receptacle for the latter, an air pump, means for operating the latter. means for rocking the receptacle connected with the operating m ans, a fluid container, a rockable support therefor, a flexible conduit connecting the ontainer and retort, and a tlexihle conduit 0 nnecting the pump and annular chamber.

In testimony whereof we have signedour names to this specification in the presence of two subscriling witnesses.
